Area of Science:

  • Biochemistry
  • Enzymology
  • Biotechnology

Background:

  • Carbohydrate-active enzymes (CAZymes) are crucial for biological processes and industrial applications.
  • Genome and transcriptome sequencing have revealed numerous putative CAZymes, but methods for activity screening are limited.
  • Efficient screening is needed to characterize these enzymes and explore their potential.

Purpose of the Study:

  • To develop a sensitive, high-throughput method for screening carbohydrate-active enzyme activities.
  • To enable the characterization of uncharacterized enzymes and crude enzyme mixtures.
  • To facilitate the analysis of enzyme function against diverse substrates and biomass.

Main Methods:

  • Developed a semiquantitative enzyme screening technique combining carbohydrate microarrays and molecular probes.
  • Utilized multiplexing capacity for simultaneous analysis of multiple enzymes and substrates.
  • Applied the method to assess activities of purified enzymes, enzyme mixtures, and crude culture broths.

Main Results:

  • The technique is sensitive, high-throughput, and requires low enzyme and substrate amounts.
  • Successfully analyzed endo- and exo-acting glycoside hydrolases, polysaccharide lyases, carbohydrate esterases, and lytic polysaccharide monooxygenases.
  • Identified substrate specificities of uncharacterized enzymes and screened fungal culture broth activities.

Conclusions:

  • The developed method offers a versatile platform for rapid CAZyme activity screening.
  • This technique accelerates the functional characterization of novel enzymes.
  • It holds significant potential for enzyme discovery and application in biotechnology and biorefining.
